FORCE-FEED FOR GRAIN-DRILLS.

SPECIFICATION forming part of Letters Patent No. 305,314, dated September 16, 1884.

Application filed Ap ril5,1s84. (No model.)

To all whom it may concern.-

Be it known that I, JOHN H. KEEDY, a citizen of the United States, residing at West Alexandria, in the county of Preble and State of Ohio, have inventedanew and useful Force- Feed for Grain-Drills, of which the following is a specification, reference being had to the accompanying drawings.

This invention has relation to force-feed IO wheels for grain-drills; and it consists in the construction and novel arrangement of parts. as will be hereinafter fully described, and particularly pointed out in the claim.

Figure 1 is a view in perspective of the feedwheel embodying my improvement, and Fig. 2 is a view of the feed-wheel in place upon the shaft below the throat of the hopper. Fig. 3

is a detail view of the feed\vheel and the washers detached from its ends.

Referring by letter to the accompanying drawings, adesignates the hopper; b, the throat of the same, and c the shaft on which the feedwheel is keyed.

The cap d and its curtain e, and the washers 2 5 ff, as well as the parts above mentioned, are

the same in construction as those parts shown in Letters Patent to D. E. McSherry, No.

97,425, of November 30,1869, on which this invention is designed to be an improvement.

The improvement herein lies in the construction of the seed-cups in the feed-wheel, which, instead of extending in spiral form eutirely across the perimeter of the wheel, as in said patent, are formed by spiral grooves g, ex,

3 5 tending halfgvay across the perimeter and mismatching the spiral grooves 71., extending from the middle to the opposite face of the wheel, the said spiral grooves g and it running in the same direction. By this arrangement a double set of cups are formed, which operate to force the grain forward continuously in a small stream, thereby securing a uniform supply of seed to the discharge.

The device is simple and certain in its action and is not liable to get out of order.

I am aware that a feed-wheel for forced-feed grain-drills has been provided with spiral grooves extending entirely across its perinieter, and has been used in connection with collars or washers at its ends, also, that a feedwheel has been provided with straight teeth extending half-way across its perimeter and arranged to mismatch, and Ido not claim either of said constructions.

Having thus fully described my invention," what I claim as new, and desire to secure by Letters Patent of the United'States, is-

The herein described force-feed for graindrills, consisting of the wheel provided with the mismatched spiral grooves g and h eXtcnd- 6o ing one-half way across its perimeter, in combination with the Washersff at its ends, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affi xed inysignature in prcsence of two witnesses.

JOHN H. KEEDY.
